Information geometry and entanglement under phase-space deformation through nonsymplectic congruence transformation
Shilpa Nandi, Pinaki Patra
The Fisher-Rao (FR) information matrix is a central object in multiparameter quantum estimation theory. The geometry of a quantum state can be envisaged through the Riemannian mani…

Information geometry of entangled states induced by noncommutative deformation of phase space
Shilpa Nandi, Pinaki Patra
In this paper, we revisit the notion of quantum entanglement induced by the deformation of phase-space through noncommutative space (NC) parameters. The geometric structure of the…
